Tuning in to magnetic ink

A new ink containing iron-oxide nanoparticles can be turned into fully printed and versatile components for cellular networks.

High-speed and on-silicon-chip graphene blackbody emitters

High-speed light emitters integrated on silicon chips can enable novel architectures for silicon-based optoelectronics. However, compound-semiconductor-based light emitters face major challenges for their integration with ...

The fine-tuning of two-dimensional materials

A new understanding of why synthetic 2-D materials often perform orders of magnitude worse than predicted was reached by teams of researchers led by Penn State. They searched for ways to improve these materials' performance ...

Building miniature optical antennas using DNA as a guide

An international research collaborative has reported a new, highly parallel technique to fabricate precise metallic nanostructures with designed plasmonic properties by means of self-assembled DNA origami shapes. The so-called ...

Pearly material for bendable heating elements

The iridescent shimmer of a string of pearls may one day be more than pretty adornment. Scientists now report in ACS Applied Nano Materials a hybrid material consisting of imitation pearl combined with silver nanowires that ...
